Abstract
Description
Claims (7)
- 腹部大動脈瘤を治療するための、カテーテルによる送達が可能なステントであって、
(a)形状記憶合金からなる複数のワイヤが編み込まれた第1のストランドを含み、その網み目構造(braid)が、それを通る血流を大きく(materially)妨げないよう十分に大きな開口部を規定する所定のピック及びピッチ(pick and pitch)を有する、第1の長さの最も内側の管状構造物と、
(b)前記最も内側の管状構造物の前記第1の長さより短い所定の長さ部分を包囲する関係で配置された所定の直径の少なくとも1つの他の管状構造物であって、前記複数のワイヤが編み込まれた第1のストランドより数が多く、やはり形状記憶合金からなる複数のワイヤが編み込まれた第2のストランドを含み、前記他の管状構造物の網み目構造が、それを通る血流を実質的に排除するように十分な小さな開口部を規定するピック及びピッチを有する他の管状構造物とを含み、
(c)前記最も内側の管状構造物と前記他の管状構造物を長手方向に伸長することによって、ステントの外径が、ステントを血管内送達用カテーテルの管腔に搭載できるよう十分に縮小し、前記送達用カテーテルからステントを放出することによって、前記外径が前記所定の直径へと再び拡張する、カテーテルによる送達が可能なステント。 - 前記最も内側の管状構造物の、前記他の管状構造物の末端を超えて延びる部分が、前記他の管状構造物が腹部大動脈瘤に跨がる(bridge)際、患者の腎動脈と患者の腹部大動脈の接合部に重なる(overlay)ように適合されている、請求項1に記載のカテーテル送達が可能なステント。
- 2つの他の管状構造物が、前記所定の長さ部分を全体的に同軸で囲む関係で配置されている、請求項1に記載のカテーテル送達が可能なステント。
- 前記形状記憶合金がニチノール(登録商標)を含む、請求項1に記載のカテーテル可能なステント。
- 前記複数のワイヤが編み込まれた第1のストランドが36のストランドを含み、前記複数のワイヤが編み込まれた第2のストランドが144のストランドを含む、請求項1に記載のカテーテルが可能なステント。
- 前記2つの他の管状構造物がそれぞれ144のワイヤが編み込まれたストランドを含む、請求項3に記載のカテーテル送達が可能なステント。
- 腹部大動脈瘤を治療するための方法であって、
(a)請求項1のステントを準備するステップと、
(b)前記ステントの近位端をプッシャーカテーテルに脱着可能に固定するステップと、
(c)前記ステントを血管内送達用カテーテルの管腔へと引き込むステップと、
(d)前記送達用カテーテルの遠位端が、治療しようとする動脈瘤の付近に来るまで、前記送達用カテーテルを血管系を通して前進させるステップと、
(e)前記送達用カテーテルの遠位端から前記ステントを放出し、前記ステントが前記動脈瘤に跨がりながら自己拡張して大動脈壁に係合する(engage)ように、前記送達用カテーテルを近位側に引き込みながら、前記プッシャーカテーテルを使用して前記ステントを固定保持するステップと、
(f)前記ステントの前記近位端を前記プッシャーカテーテルから解除するステップとを含む方法。
